6. Using the UPS monitoring software and contact signal
6-5 Using the Contact Signal
You can develop your unique system based on the following specifications to automate the process at the
power failure.
You can perform power failure and shutdown processing by allowing the system to detect the backup signal
and low battery level signal, or you can use the trouble signal to perform failure notification.
You can stop the UPS by inputting the UPS Stop Signal from the system, and remote control start and stop of
the UPS by using the Remote ON/OFF Signal.
Also, this function is valid only when “connection communication” is selected for the “switching switch”. (See
item 2 on page 35.)
1. Signal output
The UPS has 5 kinds of output signals. The output circuit consists of an open collector circuit using a photo
coupler (a kind of electronic switch).
●
Backup Signal output: BU
●
Low battery level signal output BL
Goes ON when the battery becomes weak during the
Battery Mode.
●
Trouble Signal output: TR
Goes ON when an internal failure of the UPS occurs.
●
Battery Replacement Signal output (WB)
Turns ON when battery deterioration is detected.
BU-COM ON when a power failure occurs
BL-COM ON when low battery level is detected
TR-COM ON when an internal failure occurs
WB-COM ON when battery deterioration is detected

4) After the settings are made, double-click the "Service" icon in "Control Panels".
5) Select the UPS service and click the "Start" button.
By starting the alerter service, messenger service, and event log service in advance, the UPS service
sends warning messages to the user and records a history of events such as power failures when they
occur.
When a power failure occurs, Windows shutdown is performed once the low battery level signal is
detected. If the power is restored before the low battery level signal is detected, Windows shutdown is
not performed and the normal monitoring state is restored.
